Rated 5 out of 5 by Pebbie mood stabilizer
When my dog died I couldn't stop crying and someone in my local health food store recommended Natrol 5-HTP to help my mood. I started taking it and it really helped a great deal. When I saw it in your catalog I was thrilled because it cost less than what I was paying locally even with your low shipping costs. Getting it in the mail has made it really convenient - no fighting the traffic. Thank you - it has been a great all around.

Rated 5 out of 5 by kalena Don't give up.
The non-timed release made me nauseated and wound me up instead of putting me to sleep, so I quit taking it.
After three nights with a total of 10 hours' sleep, I thought, "If I'm never going to get another decent night's sleep, I could really use something like that during the daytime."
I bought the timed release 100mg and it did help keep me more alert at work, with better concentration. Four nights later, I slept until my alarm went off for the first time in well over two years. The next night (Friday) I slept until nearly noon and woke up bounding with energy. That's another thing that hasn't happened in years.
It's an ongoing experiment. Hint: if 5-htp winds you up, don't take 12 hour timed release *at noon*.

Rated 5 out of 5 by JG000 Terrific
This supplement is terrific. I recommend it to friends and swear it by. I think the time-released formula helps it's effectiveness and increases mood stability. I often cut the pills in a half, which seems to suffice. It does everything the bottle suggests - enhances mood, helps control appetite and regulates sleep.
The one drawback I've found is some days when I don't take it I might be slightly more irritable or grumpy. I take that as a sign that it works. Swanson's pricing is the best I've found.

Rated 5 out of 5 by LivingWellinthisAge Happy that it is Time-Release
5htp is a great mood booster. I'm very happy that Natrol has produced a time-release form; this makes it very convenient to use and avoids drowsiness.

Rated 5 out of 5 by Shauna Very Happy
This was my first experience with 5-HTP. I needed a seretonin supplement. I found this one to be much more than I expected. I am very happy, calm and sleep well. I have since tried other brands, but always come back to this one. It is powerful but gentle on my system.

Rated 5 out of 5 by Deeds Good product, great price
Bought this from Swanson for less than half of what I paid in a local vitamin shop. I read reviews before purchasing - I feel it's a beneficial product for mood support. It doesn't cause jitters or any other negatives. And as a bonus, it seems to help with sleep as well as appetite (suppressant). I will continue taking this product and will recommend to others.

Rated 5 out of 5 by rbargery 5HTP Works
I have been on the product for about 6 weeks, and find I have no real food cravings at all. I began taking it in hopes it would help me fend off the nighttime snacking binges. I believe this is a product that works, and it is helping me to lose weight. Would definitely recommend it to others.

Rated 4 out of 5 by meagan the only 200 mg for the most count i can find
I take these because they are the lowest priced 200 mg 5HTP i can find, but I don't like the tablets as compared to the capsules and I don't think these are as good as the ones with the yellow label. I'd really like it if they put more 200mg capsules in a package. I also don't understand why 5HTP is so expensive. I don't know if these are working like the other brand i used to use but i tried going with them and noticed the difference. so they must be doing something.

Rated 5 out of 5 by LilyStar1 Really fantastic product
I usually get the Swanson's brand 5 htp but they were having a sell on the time release...Swanson's products are amazing but I was finding that every time I took a pill it would knock me out so i could only take it at night. With time release I can take it now anytime without feeling tired. I love this product it really helps with the lawls. My sleep is extremely restful, and my moods have mellowed in there extremes

Time release is the way to go with 5-HPT. Works well and seems to last all day. It's a keeper.

Rated 5 out of 5 by SupplementsLady Best 5 HTP for Time Release
I order often from Swanson and have enjoyed the savings and quality. They also have a large varity of name brands. I use all Swanson except for the Natrol 5 HTP because it is a time release. Well, I ran out. I have just placed my order for more. This supplement really helps me deal with stress. I'm 59 pushing 60 in June and work the 12midnight - 8AM tour 40 hours a week in a hospital. I can really feel the emotional and energy level drain when I don't use this product. Thanks Swanson for all you do for me and my family!

Rated 5 out of 5 by arkiegirl works for me
Had to buy this product because the regular 5htp was out of stock. Really can tell the difference in the time release formula in the afternoon. Take one every morning and dont get the blahs all day.
Little more expensive than regular, but well worth it for me

Rated 5 out of 5 by yogagirl works like a charm
This time released 5htp is fantastic. I take it early in the evening and it gives me a wonderful nights sleep without a hangover in the morning. The time release keeps it working all night long. I have tried many brands and by far this works the best!!!
